E.) Mesosphere, Asthenosphere, Outer layerUnfortunately there is no standard terminology for three-layered mantle. Can I be sure that the "ionosphere" and "the thermosphere" only refer to the atmospheric layers, so that you can rule out a, B, and D. "Mesosphere" can be used to refer to a layer of the atmosphere, but are also often used to refer to a mantle layer. so I'm going to go with, And even though I do not like it very much. I guess that what is meant by "outer layer" is the part of the lithosphere that does not match with the cortex of the composition.
